Tris-[(dimethyl-p-tolyl-silanyl)-methyl]-phosphine oxide is a complex organophosphorus compound with the chemical formula C24H33O2PSi3. It is characterized by a central phosphorus atom bonded to three (dimethyl-p-tolyl-silanyl)-methyl groups. The dimethyl-p-tolyl-silanyl group consists of a silicon atom connected to a methyl group, a dimethyl group, and a p-tolyl group (a tolyl group with a para-methyl substitution). tris-[(dimethyl-p-tolyl-silanyl)-methyl]-phosphine oxide is often used as a ligand in organometallic chemistry due to its ability to form stable complexes with metal ions. It is also known for its potential applications in catalysis and as a precursor in the synthesis of other organophosphorus compounds. The compound's structure provides steric bulk and electronic properties that can influence the reactivity and selectivity of the metal complexes it forms.

18758-70-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18758-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,5 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.Calculate Digit Verification of CAS Registry Number 18758-70:
(7*1)+(6*8)+(5*7)+(4*5)+(3*8)+(2*7)+(1*0)=148
148 % 10 = 8
So 18758-70-8 is a valid CAS Registry Number.
